Patent number: 9828558Abstract: The invention relates to a method for refining a feed oil having contaminants therein. In the method, the feed oil is exposed to reducing conditions at elevated temperature and pressure so as to reduce at least some of said contaminants. The resulting oil is then degassed under reduced pressure under non-oxidizing conditions and the resulting oil extracted with water so as to produce a refined oil.Type: GrantFiled: July 2, 2014Date of Patent: November 28, 2017Assignee: Hydrodec Development Corporation Pty LtdInventors: Mark McNamara, Gordon Chung, Yong Feng Wang, Michael Lucas, William Hand

Patent number: 7803633Abstract: A screening device for performing an immunoassay test to detect the presence of a compound in a body fluid. The device includes a holder for removably receiving a membrane to which the fluid has been applied. Light is directed to the membrane. A photodetector measures the concentration of the light reflected back from the membrane. Specifically, the concentrations of reflected light from a control zone and a test zone are measured. Signals representative of the measured light concentrations are applied to a processor. If a specified concentration of predetermined light from a control zone on the membrane is detected, the processor considers the test to be successful. In the test is successful, the processor, based upon the measured concentration of reflected light from the test zone, generates data representative of the presence of the compound.Type: GrantFiled: April 30, 2008Date of Patent: September 28, 2010Assignee: Cozart Bioscience LimitedInventors: Robin James Spivey, Christopher William Hand, Dene Baldwin, Osborn Pierce Jones

Patent number: 7790400Abstract: The invention provides competitive immunoassay techniques for high sensitivity detection of delta-9-tetrahydro-cannabinol (cannabis; THC) employing a carrier conjugate of an intermediate in the biosynthesis of cannabis, more particularly 5-pentylresorcinol conjugated to a macromolecular carrier via its hydroxyl groups. By employing such a conjugate with anti-THC antibody in a lateral flow immunochromatography test device convenient on-site testing for low levels of cannabis in liquid samples may be achieved. Such testing is particularly favoured for roadside testing for cannabis in oral fluid samples.Type: GrantFiled: July 1, 2005Date of Patent: September 7, 2010Assignee: Concateno UK LimitedInventors: Ahmed Mohammed Taki Jehanli, Christopher William Hand

Patent number: 6457187Abstract: A pressurized flushing system for discharging liquid into a toilet bowl. The mechanism comprises a sealed container for storing a pre-determined volume of the liquid under pressure having an inlet for connection to a liquid supply source under pressure and an inlet valve to permit liquid flow through the inlet until the pre-determined volume in the sealed container is reached. There is an outlet for discharging liquid under pressure and an outlet valve movable between an open position to permit liquid discharge through the outlet and a closed position to seal the outlet. The outlet valve is urged by internal pressure within the sealed container toward an open position of the outlet when the pre-determined volume of liquid is in the sealed container, however, an actuator normally locks the outlet valve in the closed position against the internal pressure of the container. Operation of the actuator by a user unlocks the outlet valve to permit movement of the outlet valve to the open position.Type: GrantFiled: February 11, 2000Date of Patent: October 1, 2002Assignee: Pulf Water Systems Inc.Inventors: Sven Eric Andersson, Grayson William Hand

Publication number: 20010034068Abstract: Immunoassay tests or agglutination tests run on samples of bodily fluid to detect the presence of particular compounds such as drugs in the body may be screened in the screening device. A test membrane is inserted into the screening device and illuminated. The reflected image is detected and the digitized data processed. For immunoassay tests, the digitized data is segmented and data for the test region is compared to that from the control region and the background regions to determine whether the test data exhibits any significant results. For agglutination tests, the digitized data is processed to determine the number and size of the areas of coagulation to determine whether the test data exhibits any significant results.Type: ApplicationFiled: January 12, 2001Publication date: October 25, 2001Inventors: Robin James Spivey, Christopher William Hand, Dene Baldwin, Osborn Pierce Jones
